    Hmm. Don't know. I think you need to research the prop you'll use. You want to get one with as much thrust as possible. They sell hovercraft specific ones online, for like $100-200.

    I've had a plan for a few years of making one using a plywood deck, lawnmower engine and (very) large innertube. Keep me posted on your progress. Perhaps you could more fully explain your plans.

    It depends on the HP of the Yamaha engine? Is that the 4 cycle 40 horsepower engine??
